Ketamine Therapy in California

California regulates ketamine therapy through a combination of federal Drug Enforcement Administration (DEA) oversight and state-level medical licensing requirements. Ketamine is classified as a Schedule III controlled substance under the federal Controlled Substances Act, meaning that any clinic or provider administering ketamine must hold a valid DEA registration. In California, physicians who administer ketamine must be licensed by the Medical Board of California, and the clinics themselves must comply with applicable facility licensing requirements overseen by the California Department of Public Health (CDPH) and, where applicable, the California Department of Health Care Services.

Ketamine infusion therapy in California is legally administered as an off-label use of an FDA-approved anesthetic. While the FDA has approved esketamine (Spravato) specifically for treatment-resistant depression under a Risk Evaluation and Mitigation Strategy (REMS) program, intravenous ketamine infusions are prescribed and administered at physician discretion for conditions including depression, anxiety, PTSD, and chronic pain. California law requires that a licensed physician evaluate each patient, obtain informed consent, and maintain appropriate medical supervision throughout the treatment process. Nurse practitioners and physician assistants may be involved in care within the scope of their collaborative practice agreements.

Clinics operating in California must adhere to the following key regulatory requirements:

• Valid DEA Schedule III controlled substance registration for all prescribing and administering providers
• Active, unrestricted California medical license for the supervising physician
• Proper storage and documentation of ketamine in accordance with DEA record-keeping regulations
• Compliance with California's informed consent laws and patient privacy protections under HIPAA and the California Confidentiality of Medical Information Act (CMIA)
• Adherence to facility safety standards appropriate to the level of care being provided

The regulatory landscape for ketamine therapy in California continues to evolve as the field grows and state and federal agencies refine their guidance. Patients are encouraged to verify that any clinic they consider is staffed by appropriately licensed and credentialed providers, maintains transparent treatment protocols, and operates in full compliance with both state and federal requirements. Consulting with a qualified healthcare provider before beginning ketamine therapy is strongly recommended.
